.net - SQL Stored Call not passing parameter -

-

i have sql server 2008 stored procedure when called via code shown below returns missing parameter exception @batchid parameter.

as can see passing in parameter with

cmd.parameters.addwithvalue("@batchid", batchid)

but reason not picking when making call server.

probably missing simple here, been long day.

stored procedure

alter procedure [dbo].[spisenginesixcylinderbybatchid]     @batchid int begin     set nocount on;      declare @issixcylinder bit     set @issixcylinder = 0      select @issixcylinder = tblbatches.sixcylinder         tblbatches         idbatch = @batchid      select @issixcylinder end

code

private function isbatchsixcylinder(batchid int32) boolean     dim issixcylinder boolean = false      try         using cmd new sqlclient.sqlcommand("[dbo].[spisenginesixcylinderbybatchid]", _conn)             cmd.parameters.addwithvalue("@batchid", batchid)             issixcylinder = cmd.executescalar         end using      catch ex sqlclient.sqlexception         logerror(ex.message)     end try      return issixcylinder  end function

exception

procedure or function 'spisenginesixcylinderbybatchid' expects parameter '@batchid', not supplied.

can try whether code in below snippet working?

using cmd new sqlclient.sqlcommand("spisenginesixcylinderbybatchid", _conn)             cmd.commandtype = commandtype.storedprocedure             cmd.parameters.addwithvalue("@batchid", batchid)             issixcylinder = cmd.executescalar end using

or 

using cmd new sqlclient.sqlcommand("spisenginesixcylinderbybatchid", _conn)             cmd.commandtype = commandtype.storedprocedure             cmd.parameters.add("@batchid ", sqldbtype.int)             cmd.parameters("@batchid ").value = batchid end using

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2...

i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
